A state judge blocked Mississippi’s open-carry gun law from taking effect next week, writing in a Friday ruling that the law was vague and that an injunction was needed to prevent irreparable harm.

Hinds County Circuit Judge Winston Kidd scheduled a hearing July 8 to consider more arguments about whether to extend the injunction.

Hinds County District Attorney Robert Shuler Smith requested that the law be blocked, and Kidd granted the temporary injunction during an emergency hearing.

House Bill 2 clarifies that people in Mississippi don’t need any kind of state-issued permit to carry a gun that’s not concealed.

The bill’s main sponsor, Republican Rep. Andy Gipson, of Braxton, said the law simply restates the state constitution’s right to bear arms. But some sheriffs and police chiefs worry people could become trigger-happy and hurt civilians or law-enforcement officers.
